Neural therapy multifrequency and associated systems

A therapy system (100) for applying therapeutic to the dorsal column of the spinal region of a patient, consisting of the following signals: one implantable pulse generator (101); and at least one delivery device signal (103) connected to the implantable pulse generator through the body of a cable (102) has multiple electrodes, wherein the implantable pulse generator generates a therapeutic signal biphasic high frequency having a frequency in a frequency range between 2500 Hz and 100,000 Hz and therapeutic high frequency signal is applied instead of a stimulation signal of low frequency having a frequency in a frequency range up to 1500 Hz and a width pulse exceeding half the period of the signal to replace pain relief provided by the paresthesia.
